I talk, converse and laugh to myself. Is that normal? sometimes I cant do certain things because I think people are watching me but no one be around me. Am I paranoid?? I see what other cannot. . . Am i a schizo??

@Ray-Piss I talk to my self a lot. I do this because it helps me to concentrate on the many things I am doing. I had jobs painting houses where there are many different things to do and some of them have to be done at same time. I do wonder these days when I see so many talking on their cel phones and if I saw this 20 years or more ago there would of been a lot of talking to one self :)
